Not at all, but I have nvidiaI remembered that some time ago a lot of people had this kind of problem and I also remembered a solutionThe refresh rates of your monitor may be out of syncRun xvidune in a terminal and click Cancel in the popup that pops upIn the terminal you now have the vertical and (above all) horizontal sync rates for your monitorUse these in "Section Monitor"

xvidtune only tells me something xorg.conf yet have

In the following code snippet, the only thing I've added is the 1280x800 modeline line..

Well then don't - ask!You are being helped....I did not look at the modelines so I did not see that they were almost the sameModelines should not have to be used, so I assumed you had gotten them from somewhere.....Should have asked

What Husse probably mean that if the panel do not support 1280x800 resolution, and you failed to mention it was not a widescreen means we have wasted our energy trying to solve a problem that has no possible solution. I always note, from the OEM install, the resolution, since in most cases it is set to max there. So my maximum resolution is 1280x800 and what fits my screen perfect. Try:
